This is a no-judgment zone, so if you say very easy then that's fine by me haha. I think most people will probably leave it on normal unless it gets too easy or too difficult, but I personally plan on trying on very hard from the get-go. I'm hardly a difficulty masochist, though, so I avoid games like Dark Souls since that much rage and stress and failure isn't worth it, but I do enjoy the challenge and the fear of death at every turn to some degree.
And I'm mainly talking about the five difficulties on the settings slider, not hardcoe mode such as the one in New Vegas, but we can talk about that too.
